SOMERVILLE — Singer Gloria Gaynor, best known for her disco hit “I Will Survive,” is suing a landscaping company over what she says faulty renovations at her Green Brook house, according to court documents and other public records.

Gaynor, a Newark native, claims the construction of a second-floor deck by Piscataway-based Diaz Landscape Design & Tree Service, LLC led to water leakage into her home and other problems, according to the lawsuit filed Oct. 3 in Superior Court in Somerville.

The lawsuit also accuses the company of “consumer fraud” claiming, among other reasons, it did not obtain building permits for the work and was not registered in New Jersey as a home improvement contractor at the time of the construction.

The only specific address listed for Gaynor in the lawsuit is a business address in Warren Township, but public records, including court documents and property records, confirm that the disco queen owns a Green Brook residence and filed the lawsuit.

Gaynor’s attorney, Drew Hurley, and other representatives for the singer did not respond to requests for additional information.

In November 2007, the company offered to perform certain renovations on Gaynor’s second-floor cement deck and other associated work, the lawsuit states. The company ultimately replaced the deck and performed related work to the home and property, and Gaynor paid about $38,000, the lawsuit states.

After the work was done, Gaynor “began to experience water leakage into the home as a result of Defendant’s faulty construction of the second-floor deck,” according to the lawsuit. The construction also caused “ponding of water on the deck, water damage to wood sills and supports, and the formation of mold,” the lawsuit states.

Gaynor informed the company about the problems and requested that they be repaired, the lawsuit states.

The company attempted to make repairs, but those “attempts failed and the problems persisted and continue to persist causing further damage” to the property, the lawsuit states.

An experienced building contractor recently examined the work performed by Diaz Landscape Design & Tree Service and determined that, given the faulty and defective work, the “only appropriate remedy” was replacing the deck at an estimated cost of at least $120,000, the lawsuit states.
